What Is a Digital Wallet and How Does It Work?

Digital wallets, often called X Pay wallets, are transforming how people shop in the UK and worldwide.With solutions like Apple Pay and Google Pay, 42% of UK adults were registered for mobile wallets by 2025, and adoption is accelerating rapidly across the country. These ultra-secure payment tools combine speed, safety, and simplicity, delivering a checkout experience that meets modern expectations both online and in-store.

What Exactly Is an X Pay Wallet?

“X Pay” is the term often used for digital wallets designed by leading tech companies like Apple or Google. So, what is a digital wallet and how does it work in practice? At its core, it transforms your phone or connected device into a secure payment tool. Instead of reaching for a plastic card, shoppers can store their banking details safely and pay with a simple tap.

Apple Pay, Google Pay, and Samsung Pay are the most well-known examples of this technology. By digitalising payment methods, they redefine how consumers interact with money, offering merchants a fast-growing opportunity to modernise checkout experiences.


How Does a Digital Wallet Work in Practice?

The strength of an X Pay wallet lies in its simplicity and security. The process involves three essential steps:


Adding Cards Easily

Customers enrol by scanning or manually entering card details in their chosen wallet app. The bank validates the information instantly, and the digital wallet becomes ready to use.


Faster Online Checkout

Instead of filling in lengthy forms, customers simply click the X Pay button at checkout. Biometric authentication, such as a fingerprint or facial recognition, validates the payment instantly. This creates a fluid, secure customer journey that reduces cart abandonment — a challenge highlighted in this article on abandoned carts.


Advanced Security With Tokenisation

Real card numbers are never shared during a transaction. Instead, the system generates a unique, encrypted token linked only to the device and transaction. Even if a merchant’s system is compromised, sensitive data stays protected.


Why Consumers Prefer Digital Wallets


Speed and Convenience

Digital wallets drastically reduce checkout time. In-store payments take seconds, and online purchases require no repeated entry of card details. Every second saved increases conversion rates, as discussed in our article on how payment methods affect conversions.


Strong Data Protection

Tokenisation acts as a digital vault for sensitive card details, while biometric authentication adds a personal security layer. Compared with traditional card payments, the risk of fraud is significantly reduced.


Broad Accessibility

X Pay wallets work across devices: smartphones, smartwatches, or tablets. Compatibility with retailers is growing steadily, making adoption easier for consumers across age groups.


Why Merchants Should Embrace X Pay Wallets


Meeting Modern Customer Expectations

With mobile commerce booming, offering an X Pay wallet option is essential. Younger generations, particularly Millennials and Gen Z, expect seamless, mobile-friendly payment journeys that reflect their digital habits.


Increasing Conversion and Reducing Abandonment

By removing friction from the checkout, digital wallets reduce drop-off and drive more completed sales. For merchants, every frictionless payment represents higher revenue and improved customer satisfaction.


Supporting Omnichannel Strategies

X Pay wallets align with a true 360° approach, unifying in-store, web, and app experiences. They ensure consistency across all touchpoints, a key advantage for retailers seeking stronger customer loyalty.


A Real-World Example: Sarenza’s Success

Sarenza, a leader in online footwear, processes more than 64% of its sales via mobile. Introducing Apple Pay in late 2023 brought immediate benefits:

  • Over 96% of transactions were successfully processed.
  • Adoption rates surpassed those of traditional card payments.
  • Thanks to automatic card updater functionality, churn rates decreased significantly.

With Monext’s support, Sarenza could optimise mobile checkout journeys, expand payment processing across nine European countries, and maintain secure, high-speed transactions.

Digital Wallets: More Than a Passing Trend

Far from being a temporary innovation, X Pay wallets respond to real consumer needs for speed, security, and simplicity. For merchants, adopting digital wallet solutions is a decisive step toward higher conversion rates and stronger loyalty.

As adoption accelerates globally — Juniper Research projects 60% of consumers worldwide will use them by 2026 — businesses that integrate X Pay wallets today gain a crucial advantage over competitors.
